Physico-chemical analysis and assessment of water and ground water quality parameters in Nepal: A review


Kripa Ram Mehta

Nepal is the second richest country in water resources in the world. We can see many rivers, rivulares, brooks, streams, fall, lakes and small springs. Among them, rivers are the most important water resources. But rapid industrialization and indiscriminate use of chemical fertilizers and pesticides in agriculture are causing heavy and varied pollution in aquatic environment leading to deterioration of water quality and depletion of aquatic biota. Water is one of the most important compounds that profoundly influence life. The quality of water usually described according to its physical, chemical and biological characteristics. Groundwater is an essential and vital component of any life support system. It is not only the basic need for human existence but also a vital input for all development activities. Due to use of contaminated water, human population suffers from water borne diseases. It is therefore necessary to check the water quality at regular interval of time. Parameters that may be tested include temperature, pH, conductivity, total dissolved solids (TDS), total hardness, calcium, magnesium, sodium, potassium, bicarbonate, sulfate, and chloride, sodium adsorption ratio (SAR), and permeability index can be used for irrigation suitability assessment. These parameters were used to assess the suitability of groundwater for domestic purpose by comparing with the WHO and Nepalese standards. Based on the total hardness and TDS, 96% of groundwater samples are found suitable for drinking purpose. Thus the analysis of the water quality is very important to preserve and prefect the natural eco system.
